Google Analytics Shows Clicks But Not Sessions And Other Metrics

For one of the accounts I am managing, GA is not showing session or other metrics for the clicks coming from AdWords. For all the reports inside the AdWords section of Google Analytics, the reports only show clicks, cost and cpc data. What could be wrong?

@Julien Coquet The AdWords account is using automatic tagging. The problem is that any click on the ad is being redirected to URLs which automatically strip the gclid parameter. Is there something I can do here or it's the time to contact the tech team?
